I mentioned this before, but the real proof that the touch bar isn't for professionals is that you can't buy an Apple keyboard with the touch bar. Local labor laws require that I have a "external" keyboard when working at my desk, so the touch bar is pretty worthless, unless it was available on the standard alone keyboards as well, and it's not.
Personally I prefer the old keyboard because I find it easier to change volume and brightness using a key and not a slider, but that's personal preference.
